w i WILLAED.

. Be itfknownthat I,W1LLIAM H. WILLARD, of Gleveland,fin ihecountyof Cuyahoga andl j State of Ohio, have invented a new and useful Improvementfor Adj usting'Propeller-VVheels; and-Idomhereby declare that the followingis a full, clear,"and exactdescription of `the conjsltructicm` and :operation of the same, reference j eing had tothe annexed drawings, making a i part of this specitication, in whichf Figure l isaperspective view.- Fig. 2 is a i :longitudinal section, the dotted lines representingthew'h lflowered.` Fig. 3 is a transtlionl` `"seenirom thelinc X X in.

.tisa view of` the bed-plate A j A g. his aview .of apartfof the. `insidepacking-box, B, andthe slide C,which` covers the slot D. `1` Fig. 6 is aview of the outside slidexandpackenE.

` `1 The natureof my invention consists in providingan oscillating bed-plate on whihthe engincsits, and.` the sternpostfof the-vessel i .j with aslot andisliding packing-box to allow -the adjusting ofthe propelling-wheelto` the draft of water, thereby obtaining the .ad-

" i draft ofthe vessel, be the same light or heavy lade`n,and is intended for Hat-bottom craft, but may be applied tocraft of any construcytion.

j and `use my invention, I will proceed to describe its construction and operation. .i Iconstruct abcd-plate, A, resting on jourhals I I, whichhas an oscillating movement, allowing theend ofthe shaft S, on which the i propelling-wheeljW is attached, tol be raised or lowered as circumstances may require. The engine and machinery are placed on this bedplate and are subject `to the oscillating movement, and are kept in'a right-angle position to j the shafts. `There are two rods,R R,passing through .thebearings O O, and secured to the journal G', for the purposeof supporting the shaft andrelieving thebearings at MM. 'They tomli may concern,.-

f vantage of submerging the wheel to suit the To enable others skilled in the art to make of the set-screws N N. I also constnct a pack- Y ing-box, 13, placed on the inside of the sternpost P, having a slot, D, of sufcientlength to allow the upward and downward movej ment of the shaft. This slot is covered with a rotating slide-plate,0,to prevent the ingress of water, and is provided with a journal, G, for the shaft S. This journal is inclosed in the cylinder H, which rotates upon it.

ment of a circulan ratchet,L,worked by means of the gear-wheel K on the cross-shaft T. This is fon the purpose of raising or lowering the propelling-wheel, which may be secured at anyl point desired by the Vratchet-wheel and dog y e. There is also on the outside of the F, forthe same purpose as the inside one, either or both of which may be used,at the option of the builder.

on' the underside of the keel, and is secured to it by a joint, c. To `the back end-of' this is the rudderpost Q, and has a socket, b, for the end of the shaft S to rest in. This is for the purpose of protecting the wheel and guarding against any obstruction-as, for instance, in passing over a stone the wheel is raised up.

. Now, when the vessel is light or unladen, and it is desired, the wheel'is lowered by lifting the dog z and turning the cross-shaft-T,

of the propellingwheel under all circumstances. f v

What I claim as my invention, and desire to secure by Letters Patent, is-

The combination 4of the voscillating bed-plate A, rotating packer B, andgnard or fender V, constructed substantially` as described, and `for the purposes set forth.

There is attach ed to the slideplate C thesego stern-post another slideplate, E, and journal Y I also construct a fender y or guard, V, plaeedin a groove running along attached a slide, U, which plays in a groovein andthe wheel is submerged,"thereby gaining` the desired subject of obtaining the full power
